Managing Temperature Sensitivity in Multiple Sclerosis


Heat Sensitivity in MS
People with MS are often sensitive to heat. Even a small rise in body temperature can worsen symptoms. Warm weather, hot showers, heavy meals, and exercise can all cause problems.

Worsened Symptoms
Heat can trigger MS symptoms and make them worse. Things like fatigue, pain, blurred vision, muscle weakness, and balance issues can all be brought on from heat. Cognitive difficulties like focus and memory problems can also occur.

Exercise Tips
Exercise is important, but overheating should be avoided. Try exercising outdoors in the early morning or evening when it tends to be cooler. Swimming in unheated pools and wearing breathable clothing can help.

Cooling Strategies
Cooling collars and vests can help manage body temperature. Wearing fabrics like cotton and linen, using LED lights instead of heat-emitting bulbs, and staying hydrated are also effective strategies.

Dietary Changes
Eating lighter meals, such as salads and fresh fruits, can prevent heat buildup. Avoid alcohol, as it can worsen symptoms.

Home Environment Tips
Keep your home cool by using fans and unplugging electronics when not in use. Cooling sheets, towels, and pillowcases can also help manage body temperature.

Gadget Considerations
There are many cooling gadgets available for MS patients. Research options thoroughly, as prices can vary. Some organizations offer programs to distribute cooling vests.
